des variablen » der variablen, die variablen, und variablen
variablen aid » variablen und, variablen a, variablen aa
l afrique » en afrique
aid does » card does, aid days, aid do
does csr » does cash
2 de » 2 die, 2 der
_ de » _ der, _ den, _ do

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: typologie des variablen aid does csr communications ((2 de) OR (_ de)) developpement l afrique.~.
• Adding a wildcard symbol may retrieve word variants: typologie des variablen aid does csr communications ((2 de) or (_ de)) developpement l afrique.*.
